Hello all,
 I know this seems to be a pretty consistent problem, but I have everything set up and am not able to consistently click and drag. Clicking works fine, but trying to write/draw/drag anything does not work well at all. My setup is this:

1)  Pen: http://cgi.ebay.com/IR-Pen-Infrared-LED-Pen-4-WiiMote-FREE-Shipping_W0QQitemZ230314452681QQ
2)  Wiimote location: Set on a projector that is hanging from the ceiling. Like this picture, only without the mounting   device: http://www.boonjin.com/smoothboard/index.php?title=Image:Holder4.jpg
3)  Software: Smoothboard
4)  Computer: laptop with class 2 bluetooth
5)  Surface: pull down projector screen

Other possibly important facts:
   -the best utilization I have gotten is 41%. Is this sufficient? I have tried different placements, but this is the best    I've gotten without getting a way to hang the remote from the ceiling somehow.
   -The baterries on the Wiimote are at 50%
   -the laptop that everything is connected to is at the back of the classroom (~20ft from the projector). I know this   isn't a problem on paper because both my laptop and the Wiimote should have a range of 30m, but I wanted to include all relevant details.
   -the pen is new as of 2-3 weeks ago, and has not been used alot since, so it should be fine battery wise


Any help in eliminating any of the above things as sources of the problems would be helpful. One thing I know I do need to do is work on the math on wiimote placement(d=2h), which I haven't checked yet. Any suggestions would be greatly appreciated.

Hi,

From your description, it is most probably due to the IR point detected by the Wiimote to be too low in intensity. Therefore, the IR detected will not be consistent.

Please check that the Smoothboard's IR sensitivity level is set to maximum. (Settings->Wiimote->IR Sensitivity)

For your situation, since it is a fixed setup you should try to further increase the tracking utilization. The IR pen's batteries should also be checked to ensure that it is not the cause of your issue.

Btw, how large is your screen?

Regards,
Boon Jin

Hi

I noticed that your battery level is at 50%.  If this is the indicated level as shown in smoothboard that might be your problem.

Try this - after starting up smoothboard.  Close it and restart smoothboard with wiimote still connected.
This will show the actual battery level.  The battery level is not real time and when it is pairing it requires lower current but when it runs smoothboard a higher current goes thro the wiimote. The battery level when smoothboard first starts up is the battery level just before the wiimotes stabilises.  If you restart smoothboard it will show the actual battery level.

By any chance are you using a AC-Dc convertor.

Thanks for the replies, and sorry for the delay in response.

First of all, Boon Jin- you asked how big the screen was: it is about 43 in(111cm) high x 57in (146cm) wide.

In response to your other ideas, I have the smoothing turned all the way up, and that hasn't appear to have any effect. I will try to check out different batteries/diff power source for the pen this weekend and report back.

Other than that- you mentioned increasing the tracking utilization- other than placement  of the wiimote, is there any way to majorly increase this?

Hagoh- thanks for your input too. I have an extra set of batteries (for the Wiimote), and will be trying to see if new batteries have any impact. I am not using a AC-DC converter, as you asked about. I may look into getting one eventually, but right now I was waiting to get everything working well before investing more money.

Thanks

A quick update- I tried putting in new batteries for the Wiimote, with no success. However, I then pulled out a camera phone to check if the pen was still working, and it barely was visible, so I'm fairly sure its a matter of needing new batteries/a new pen. I haven't had this pen long at all, so I think I'll invest in something more high quality. Any suggestions would be appreciated, but I'll make sure and check out the Market Place soon

I learned the hard way (bringing it out to show off in public) that the wiimote will not track in dragging lines if the pen battery is low. I replaced the batteries and it worked like a champ.
